English

Subject field(s)
  • Motor Vehicles and Bicycles
CONT

An electric repower—sometimes referred to as an electric conversion or retrofit—involves [removing] a vehicle's internal combustion engine that runs on a fossil fuel like diesel, gasoline, propane or natural gas and replacing it with an electric drive system, transforming the vehicle to one that is fully battery-electric with no tailpipe emissions.

Key term(s)
  • electric re-power
  • re-powering

French

Domaine(s)
  • Véhicules automobiles et bicyclettes
DEF

Remplacement de la chaîne de traction thermique qui équipe un véhicule par une chaîne de traction électrique alimentée par des batteries ou par des piles à hydrogène.

OBS

conversion électrique : désignation et définition publiées au Journal officiel de la République française le 30 avril 2025.

Another innovation is the back-surface reflector(BSR). Even in photovoltaic devices operating at theoretical maximum efficiency, less than 40% of the light to which it is sensitive is absorbed by the cell and converted to electricity. The rest travels through unabsorbed and becomes a system loss. However, the BSR reflects this light back through the cell for a second pass, which greatly increases the conversion efficiency. Also, the BSR reflects radiation to which the cell is not sensitive. This radiation is called out-of-band radiation, and cannot be converted to electricity with this given material bandgap. By reflecting the out-of-band radiation back through the cell, it passes back out the front to the heat source where it is recycled.(Essentially, it helps keep the heat source hot so less fuel is required.)

Domaine(s)
  • Photo-électricité et optique électronique
  • Énergie solaire
  • Engins spatiaux
  • Stations orbitales
CONT

On réduit l'échauffement de ces photopiles en réalisant un réflecteur dans le contact arrière [...], ce qui favorise aussi la création de porteurs de charge aux longueurs d'onde voisines de celle correspondant au seuil d'absorption intrinsèque, en augmentant leur trajet optique. On obtient le réflecteur par une métallisation à l'aluminium; le contact arrière est constitué d'un dépôt multicouche : Al-Ti-Pd-Ag.
